Anyone having problems with 3.0.1.? I'm getting major buffering issues when trying to playback content from my iMac (wired) to the Apple TV (wireless). This seemed to have started with 3.0.1. It's like the Apple TV forgets what it's receiving. I can't fast forward without it stopping and returning to play the file. I even cleared the entire Apple TV hard drive and changed channels on my AirPort Extreme. I firmly believe it's not a network issue as I'm running a simultaneous dual-band AirPort Extreme router with both an 802.11n @ 5Ghz and an 802.11n/802.11g/802.11b @ 2.4Ghz network. And I'm not experiencing any other problems on the network. Nothing seems to fix it. I've also did the format and reinstall firmware 1.0 then upgrade to 3.0.1 twice. Additionally, it tells me that certain files are not compatible with the Apple TV even though I know they worked fine with pre 3.0. It says it cannot playback the file, but the file plays fine on both my Macs and will even sync to my iPhone. The files in question are both SD and HD files including some downloaded directly from the iTunes Store. Any thoughts?
